2). It is apparent from the RREF of AT, that its 3 columns i.e. the 1st, 2nd and 4th columns of AT are linearly independent and its 3rd column is a linear combination of its first 2 columns. Therefore, 3 rows of A are linearly independent and since the 4th row of A is a zero row, hence the first 3 rows of A are linearly independent.
Hence the 2 bases of the row space of A are the sets { (1,0,1,0,1),(0,1,-2,0,3),(0,0,0,1,-5)} and {(1,0,0,0,0),(0,1,0,0,0),(0,0,1,0,0)}.
